Christina left Hex at the beginning of season two as she wanted to do something different, but she stayed for three episodes for continuity reasons. Her character Cassie was replaced by a new character Ella Dee, played by Laura Pyper.
(On 'Hex')Christina: I don't know how I got through it! I did just pace myself, I made sure I didn't have crazy nights out, my weekends were just looking over the scripts and knowing what I was doing the next week and then it was just maintaining my energy levels, lots of coffee, chocolate, being so passionate about a project I loved every single minute of it, the cast and the crew made it so easy to get through it.
(On her character Nora in 'He Knew He Was Right')Christina: Nora is passionate but calm. She is the voice of reason between her and her sister. She's very much the second child and knows when to keep her mouth shut, although she tries to give a lot of advice.
(On playing Cassie in 'Hex')Christina: I love all the levels of Cassie, but I did like playing bad assed Cassie 'cos she finds it so difficult to be herself, to find herself, to express herself, so it was quite liberating.
